This is a multi-case from Tokai On Air. I purchased it last year at the official shop in Okazaki. The seal has been opened, but it has never been used. Please understand that it is not completely new. Retail price: 1650 yen x 4 If you only want to purchase one, I will sell it for 1500 yen. If you wish to purchase only a part of the set, please let me know in the comments. #TokaiOnAir #Goods #Official #Tetsuya #Shibayu #Ryo #Toshimitsu
